Latest Patents
One of his key patents is titled "Digitally-intensive transmitter having wideband, linear, direct-digital RF modulator." This invention features a wideband, linear, direct-digital RF modulator (DDRM) designed for a digitally-intensive transmitter (DTX). The patent includes an interpolation filter that effectively suppresses sampling replicas in the output RF spectrum of the DDRM. Additionally, the invention employs an in-phase/quadrature (I/Q)-interleaving RF digital-to-analog converter (RF-DAC) to avoid complications associated with using separate I- and Q-path RF-DACs. Each unit cell of the interleaving RF-DAC can produce four unique non-overlapping waveforms, covering all four quadrants of the I/Q signal plane. In one embodiment, the interleaving RF-DAC consists of three parallel-connected RF-DACs that operate with a multi-phase set of local oscillator (LO) clocks. This design effectively cancels 3-order and 5-order LO harmonics generated by the RF-DAC unit cells' interleaving logic, preventing 3-order intermodulation in the DTX's final stage RF power amplifier. Mohammed holds 1 patent in total.
